What's the difference between a waist money belt, a neck wallet, and a leg pouch?

A waist money belt straps around your waist under your shirt and lies flat against the abdomen or lower back. A neck wallet hangs from a cord around the neck and sits against the chest under a shirt. Leg pouches strap to the thigh or calf. Waist belts hide most easily under loose clothing; neck wallets are quicker to access at airport counters; leg pouches are bulkier but useful in hot climates where you wear loose pants.
